take a look at this link reset network settings http://www.apple.com/support/iphone/assistant/wifi/#section_5
My bad, it doesn't really give you the details that you were looking for.
For wifi - you would have to reenter the password. I'm not sure about celluar data.

Thanks, razmee209. I don't know why Apple doesn't list more detailed information on this, since it sounds like a pretty big thing, maybe not as big as resetting the phone.
I don't want to try it and then find out my phone won't be able to connect at all, LOL.
